ПВДФ

Excellent weatherability of PVDF DS201 PVDF is polymerized by VDF (CH2=CF2), whose macromolecule is made of – CH2-CF2- REPEATING UNIT. C-F bond makes PVDF with the heat-resistance, chemicals resistance and UV-resistant properties. A unique washing process is used to ensure the cleanliness of PVDF DS201. Therefore, PVDF DS201 is a high purity PVDF homopolymer with the inherent excellent weatherability.
